Title: Device for securing a photographic camera on a tripod or other support
IPC: F16M11/04
Filed: 1955-08-24
Abstract: 780,142. Stand heads for photographic cameras. HEIDECKE, R., and FRANKE, H., [trading as FRANKE & HEIDECKE PHOTOGR. PRAZIONS-APPARATE.]. Aug. 24, 1955 [Sept. 10, 1954; June 7, 1955], No. 24348/55. Class 97(1) A device for securing a photographic camera on a tripod or like stand comprises a peripherally grooved disc secured to the camera, a pair of parallel guide rails on the tripod engageable tangentially with groove, and means for limiting movement of the disc along the rails in one direction and for locking the disc within the rails at the end of the said movement. As shown in Fig. 3, two parallel guide rails 6 are secured to a cylindrical member 4 which has a threaded opening 5 by which it is fixed to the tripod. Each rail 6 has a guide portion 7 engageable with a groove 3 on a disc 2 fixed to the underside of the camera (not shown). The disc 2 is pushed along the guide portions 7 until it engages stop portions 8. A leaf spring 10, carried by the member 4, carries a plate 12 having a lip 13. Normally the plate 12 is clear of the path of the disc 2, but after the disc has been inserted, a lever 15 is operated and an eccentric portion 16 thereof engages the plate 12 to force it into contact with the disc 2. The disc is thus held firm on the guide portion 7, and is prevented from coming out of the guide portions by the lip 13. In a modification, the plate 12 is omitted and the spring 10 has a stirrup shaped portion which embraces the disc when it is in locking position. In a further modification, the lever 15 is recessed to house a spring-urged pawl which engages a notch in the bearing pin of the lever 15 to hold it in the locked position. In this case, lever 15 has a squared end which engages leaf spring 10 to hold the lever in its unlocked position.

Title: Improvements in or relating to aeroplanes
IPC: B64C21/02
Filed: 1937-09-07
Abstract: 497,500. Slotted aerofoils. ROSE, W. K. Sept. 7, 1937, No. 24419. Convention date, Nov. 10, 1936. [Class 4] An aeroplane wing comprising a plurality of vanes or blades forming passageways therebetween extending through the wing from the lower to the upper surface thereof, the cross-section of the passageways gradually diminishing from inlet to outlet and being such as to present no appreciable straightline passage for air therebetween is characterized in that each passageway has as its mean line a segment of a flat spiral. Wings 2, 3, Fig. 1, comprise fixed trailing portions 6 and wing tips 5 and spanwise elements 11 .. 15 comprising bearing elements 20 .. 24, Fig. 2, rotatably mounted in fuselage and wing tip. In one extreme position, Fig. 2, the adjustable elements provide a continuous or substantially continuous upper surface and a discontinuous lower surface. The trailing wall of leading edge section 10 and the leading wall of the adjacent section 12 define an upwardly and rearwardly directed slot, and similar slots are formed between the adjacent walls of successive sections and between the trailing wall of the last adjustable section and the leading wall of the fixed trailing part 6 of the wing. The centre line of the slot is curbed to subtend an angle of substantially 90‹ and forms a segment of a logarithmic spiral as shown in Fig. 5. The flap 17 with a slot 18 is fitted in portion 6. The several sections in the two wings are conjointly operated through irreversible wormgearing by a series of bell-crank levers pivotally mounted in the fuselage and of which one arm engages a slot 40 in each section and the other a link 45 connected to the control transmissionstops in the latter may be constituted by the ends of the slots which limit the movement of the adjustable sections to a maximum which is not such as to permit the exit opening to overlap the inlet. The pivotal points of the sections may be so chosen that the forward lower edge of each section projects below the normal undersurface contour, Fig. 5. Alternatively these edges may be rounded as shown in Fig. 7 which illustrates a wing having fixed slots. The above described arrangements are designed to increase the value of the lift/drag ratio and may by differential control of the slots on the two wings effect lateral control but other arrangements of slot such as slots directed downwardly and forwardly or upwardly and forwardly may be used to reduce the lift /drag ratio at will.

Abstract: 1,097,284. Data storage. INTERNATIONAL BUSINESS MACHINES CORPORATION. June 3, 1966 [June 18, 1965], No. 24734/66. Heading G4C. Storage areas have respective associated status registers, each containing at least one bit associated with each other area, each register being enabled by the accessing of the corresponding area and each bit being enabled when its associated area is occupied, a given bit being switched on when both it and its register are enabled. Each storage area has an associated tag bit set to 1 if the area is full (occupied) and an associated column of a matrix of latches, (leading diagonal missing). Each row of the matrix corresponds to a respective tag bit. When a storage area is filled, its full tag is set to 1, as are all latches in its column which are in rows corresponding to a tag bit equal to 1. When a storage area is emptied, the tag bit is set to 0, as are all latches in the matrix row corresponding to that tag bit. The tag bits and matrix outputs are fed to logic which indicates which of those areas which are full was filled first, second, third, fourth or last, to control read-out in a desired sequence e.g. first-in, first-out or last-in, first-out. The store may comprise magnetic cores or latches. The matrix may consist of cores. The matrix bits and tag bits may form part of a control work associated with a store segment, and this word may be recirculated in a delay line or be stored on a magnetic drum or tape.

Title: Process for the manufacture of animalysed artificial textiles and cellulosic films
IPC: D01F1/10
Filed: 1937-09-11
Abstract: 501,611. Artificial filaments, films, etc.; resinous condensation products; dyeing processes. SOC. INDUSTRIELLE DE MOY, and BURET, R. Sept. 11, 1937, No. 24828. [Classes 2 (ii), 2 (iii), and 15 (ii)] Regenerated cellulose threads, fibres, ribbons, and films possessing a high affinity for wool and silk dyestuffs, are obtained by incorporating in the cellulosic solution from which the materials are formed, a synthetic resin obtained by condensing an aldehyde with a phenol containing a substituent group in para position to the hydroxyl or a mixed synthetic resin obtained by reaction of a phenol or a phenol substitution derivative on a resin of the ureaaldehyde type; or by reaction of urea on a resin of the phenol-aldehyde type. Thio-urea may be used instead of urea. The resins employed are resistant to oxidation and have little or no tendency to discolour the threads containing them. These resins give a green colouration when treated with concentrated sodium hypochlorite solution whereas resins which readily darken by oxidation give a red colouration. In an example, a syrup is obtained by heating a mixture of p-cresol, formalin, and caustic soda solution, distilling volatile constituents, and adding more caustic soda. The syrup is further diluted with caustic soda solution and added to viscose at any stage of preparation of the latter. The viscose is spun into an acid-salt bath and the threads produced are subjected to finishing treatments. In another example, urea, formaldehyde solution, and caustic soda are heated together on a water-bath. After the reaction has slackened, phenol is added. Part of the mixture is distilled, more caustic soda is added to the syrup, and before use the syrup is mixed with dilute caustic soda solution. The diluted syrup is added to viscose which is spun into a bath containing sulphuric acid and sulphates. The threads are desulphured and bleached. In another example, formalin is mixed with thiourea, glycerine, and hydrochloric acid. The mixture is heated to boiling and then left to cool. While still hot, there is added to the solution a quantity of molten phenol. Caustic soda solution is added when the reaction has ceased. The diluted syrup is mixed with viscose which is then spun to form filaments. These are cut to staple fibres which may be mixed with wool. Thread or fabric containing the mixed fibres may be dyed in a single bath. Dyes may be added to the cellulosic solution before spinning. The solution may also contain additions of softeners such as glycerine, glycol, or camphor, or pigments, mordants, or oils. Specification 501,603 is referred to.

Title: Electromagnetic relays
IPC: H02H3/26
Filed: 1925-10-10
Abstract: 263,956. British Thomson-Houston Co., Ltd., and Wheatcroft, E. L. E. Oct. 10,1925. Electromagnetic and magnetic switches; induction relays.-Electric relays for use for example in the protective arrangement described in Specification 257,699 are so arranged that with normal directions of currents in their windings the normally-balanced magnetic forces act on the movable relav element so that it is in stable equilibrium and any small movement caused by a small dissimilarity in the operating forces would tend to cause the return of the movable element to its zero position. In the relay shown in Fig. 1 for alternating current circuits the polarities produced in the fixed coils 21, 22 and the movable coils 16, 17 on the balance arm 11 are as shown for a given instant so that the repulsive forces between the pairs of coils maintain the movable contact 12 in a central zero position between the fixed contacts 13. Any slight displacement of the coil by increasing the distance between the coils exerting the greater repulsive force and decreasing the distance between the coils exerting the lesser would thus tend to restore the relay to its normal position. An operation of the relay takes place with reversal of either of the repulsive forces and if both are reversed owing to the instability of the balanced arm in this condition, operation takes place on any slight unbalance between the forces, which if not inherent from manufacture, could be purposely introduced. The relay coils surround fixed magnetic cores 18, 19 and for direct current working the fixed coils may be replaced by permanent magnets of suitable polarity. In the modification shown in Fig. 2, the relay coils are wound on suitable cores and act on an induction disc 23 which is shaped at 25 adjacent to the cores so that the relay operates in the manner described. A damping magnet 24 is provided in this form.
